How can I send basic authentication with request?

[Jones-S]

Hi there

I am trying to set up a proxy where I pass on the path of the request and send Basic Authentication headers along.

How could I achieve this? I thought something like this should work:

$response = $proxy
	->forward($request)
        ->filter(function ($request, $response, $next) {

		$method = 'GET';
		$uri = 'http://cms.local.test/api/pages/';

		$request = new GuzzleHttp\Psr7\Request(
				$method,
				$uri,
				[
				  'auth' => ['myusername', 'mypassword]
				  'Content-Length' => 30000, // a random number? How could I fix this issue that a length is required?
				],
				$request->getBody()
		);

    // Proceed with the rest
		$response = $next($request, $response);

    return $response;
  })
  ->to('http://cms.local.test/api/pages/');

// Output response
(new Zend\HttpHandlerRunner\Emitter\SapiEmitter)->emit($response);

If I run this I get 'Unauthenticated', which I would get if I request the given URL without a password and without a username.

Interestingly, if I change the user to a wrong username, I do get The user \"mywrongusername\" cannot be found. So I assume that the whole auth headers are NOT sent along.

How could I send Basic auth to the final URL?

Also I had the problem that I when I create a new guzzle request that I have to repeat the request URL. Is there a smarter way to do that?

Thank you for your help. cheers

PS:If I leave out the Content-Length part I get an error that this is required. What should I set there?

$proxy->filter(new RemoveEncodingFilter())->filter(function ($request, $response, $next) use ($path) {
            $username = 'admin';
            $password = 'admin';
            $request  = $request->withHeader('Authorization', "Basic " . base64_encode("$username:$password"));
            $response = $next($request, $response);
            return $response;
        });
